Elegant Grunge Theme incompatibility

I’ve recently discovered that the theme I’m trying to set my blog up with, Elegant Grunge, is not totally compatible with the system at Squid. According to the support, it requires a “version of PHP with PCRE at least version 7.2 19-Jun-07” in order to have the photo frames render properly. Unfortunately, the Squid version of PHP is older and can’t run it. According to the email I got this morning they’re not willing to update at this time.

I know this is a popular theme. Has anyone come up with a work around? I choose it partly because I love the look of the frames.
